BINDER.

SPECIFICATION forming part of Letters Patent No. 486,989, dated November 29, 1892.

Application filed June 25, 1892. Serial No. 437,958. (No modeLl To all whom, it may concern,.-

Be it known that I, CHRISTIAN H. STOELTING, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improveinentsiu Binders; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which ro form a part of this specification.

' This invention has reference to that class of temporary binders which comprises, ina binder, two covers, rods secured to an edge of one of said covers and adapted to be inserted through suitable openings in the corresponding edge of the other cover, and

' means for detachably securing or locking said removable cover to said rods at any desired point on said rod, the temporary [iles 2o being placed over the rods between the covers and bound `'together by forcing the edges of said covers iirmly thereupon and securing or locking said covers in this position.

The present invention consists in the improved means for looking or detachably securing the removable cover of a binder of the class described upon the rods over which the tiles are placed, and also in the features and details of construction hereinafter described,

3o and specifically pointed out in the claims.

In the drawings', Figure l is a perspective View of a temporary binder embodying my invention. Fig. 2 is a top plan view of the removable binding-piece inclosed in canvas and showing the escutcheon-piece. Fig. 3 is a similar view of said binding-piece, the escutcheon plate and canvas being removed. Fig. 4t is a similar View of the same piece, the cap or cover thereof being removed, so as to 4o show the locking-bars, said bars beingin their retracted or free position. Fig. 5 is a view thereof similar to Fig. 4, showing the bars in their cast or locked position. Fig. 6 is a sectional view on the line 6 6 of Fig. 2. Fig. '7

illustrates a modified form of the locking device, the bars being retracted. Fig. S shows the same modification, the bars 'being cast.' Figs. 9 and l0 illustrate another modification, showing the bars retracted in the go former and the bars being cast in the latter site sides of said canvas View. Fig. 11 is a transverse sectional view on the line 1l 1l of Fig. 5.

In the drawings, A represents the under or lower cover of a temporary file, which may be of any approved construction, with binding-rods B rigidly secured in and projecting laterally from one end thereof.

C represents as a whole the upper cover of a temporary file comprising a cover proper C and a binding-piece C2, united to the cover 6o proper by means of any flexible hinge. Inv the preferable construction illustrated both covers are inclosed in canvas or other suitable material, the canvas inclosing the upper cover extending continuously over the cover proper C and the binding-piece C2, the oppobeing united by a seam c between said cover proper and said p binding-piece, thus providing a suitable and convenient hinge. In the binding-strips C2 7o holes or apertures c are provided, each solocated as to receive one of the binding-rods B.

The construction of the binding-strip C2, whereby the same is adapted to be detachably secured to the binding-rods B, is as follows: Said binding-piece is made in two separate parts', a main or body part c2 and a cap or cover therefor c3. The body of said binding-strip is preferably made of suitable sheet metal, the turned up parallel sides c4 of which 8o are at right angles with the bottomV thereof, and thus form a groove or recess C3, into the ends of which suitable blocks or filling-pieces c5 are fitted flush with the tops of the sides c4. The cover or cap c3 for said body portion is preferably constructed, as shown, of suitable sheet metal with edges turned at right angles, forming sides c6, adapted to embrace the sides c4 of said body portion, the sides c(i of said cap extending Hush with the under surface 9o of said body portion. The turned-down sides c6 of said cap or cover will thus reinforce or strengthen the sides o* of the body portion. It is not essential, however, that said cap be constructed as described, as a iiat cap or cover 95 not having the sides c6 and adapted to close the top of said recess may be employed if deemed desirable for any reason. The cap or cover is secured to the body portion of the binding-piece by screws or rivets c7, the heads roo of which will preferably be so made as to be flush with thetop of the cover or cap. Holes will also be formed in said cap or cover of the same size as the holes or apertures c in the body of the binding-piece and in such position relative thereto that the rods B when 4inserted therethrough will be perpendicular to the sides of said binding-piece. Into the groove C3., formed in the body part of the binding-piece c2, as above described, are fitted two locking-bars D, both adapted to move longitudinally therein independently of each other. Adjacent to the rods B or to the holes c', through which said rods pass, said barsD are cut away in such manner as to form inclined surfaces d on said bars, which when said bars are forced in the proper direction will engage the rods D and serve to wedge said bars between the sides ofthe bindingpiece 4G2 and said rods, thus clamping said binding-piece firmly in position upon said rods D. Movement of said bars in the opposite direction will likewise disengage them and allow the removal of said bindingpiece from or their adjustment upon said rods. In order to permit the movement 'of said bars relative to the stationary screws or rivets c7, said bars are cut away adjacent thereto, as shown at d', in such manner as to yallow de- -sired movement of said bars. Preferably corresponding parts of the two levers are made to register when said bars are in the middle point of their movement, thereby producing greater symmetry in said bindingpiece.

In the preferable form of the device illustrated in Figs. l to 5 of the drawings, both inclusive, the locking-bars are cast and retracted by means of a key E, having lugs or lateral projections e, adapted .to engage notches e', formed in said locking-bars D,so that as said key is turned it will force said bars positively in opposite directions. A projection e2 at the end of said keyis fitted to a circular hole e3 in the bottom of the main part of said binding-piece and acts as a pivot on which said key turns, said key being thereby held against bodily longitudinal movement with either of said bars and insuring that said bars will be moved equal distances in opposite directions by the turning thereof. In order that said key may not interfere `with the longitudinal'movement of said lock-bars, the corners of the notches e are cut away or beveled, as shown at @4. Moreover, in order to allow the insertion of said key into operative position, it is necessary that when said bars are fully cast or retracted the beveled sides of the notches of said bars, respectively, which pass nearest to the axis of rotation of said key shall not approach nearer thereto than a distance equal to one-half of the thickness of said key. Preferably the angle of said bevel will be about forty-five degreesto the sides of the lockingbars D. A circular hole c5, having a diameter equal to the width of the key between the outer edges of the projections e thereof, is provided in the cover c3, which likewise is to allow the insertion of said key into operative position.

In the preferable form of the device springs are applied to the locking-bars in such manner as to tend normally to cast said springs or to maintain them when cast in such cast position. In the construction shown wire springs F are applied, one to an end of each of said bars, said springs being inserted between the respective ends of said lockingbars and the pieces c5, which close the ends of the grooves in such manner that they will tend to cast said locking-bars. This construction has two obvious advantages: First, when the locking-bars are cast they will counteract the elfect of any jar, as from dropping thebinder, which might tend to disengage-the frictional contact of the locking-bars and binding-rods, and, second, when said bars are retracted said springs tend to maintain them v.normally in position to permit the insertion of the key to cast said springs and lock .the binder.

In the preferable form of the device an eseutcheon-plate G is provided,said plate being secured to the upper surface of the binding-piece after the same has been assembled and inclosed in the canvas covering, whereby it is attached to the cover proper, said plate being apertured to correspond with the .binding-piece. This escutcheon-plate is primarily for thepurpose of a finish to the bindingpiece, serving to cover raw,ragged, or drawn edges of the canvas when unfinished holes are cut therein, as around the keyhole, the holes for `the passage of the binding-rods B, and the like.

In the form of the device illustrated in Figs. l to 6, both inclusive, said .escutcheonplate is constructed and answers the purpose as follows: The hole in said plate for allowing the insertion of the plate comprises inner circular sections g, having a diameter .equal to the width of the key above the flanges c of .the key E, and outer circular sections g', sufticiently large to admit the passage therethrough of the projections c of vthe key. Moreover, the width of the lugs e is equal to Athe distance between the inner surface of the bottom of the binding-piece and of the escutcheon-plate, respectively. Thus whensaid key is turned after being inserted in the lock the lugs e thereof will project beneaththe edges of the inner sections g. ltIoreoventhe relation of the sections g and g to each vother and to the notches e in the locking-bar is such as to allow the insertion of the key into operative position when the locking-bars D are in their normal retracted positionand such that as said key is turned beyond the point necessary to fully retract the lockingbars the projections c of the key will pass beneath the sections g of the escutcheonplate, so that said key will form a handle whereby the removable cover C may be conagain inserted when it 'tion of veniently handled. The relation of said parts is such, moreover, that when said cover is locked in position upon the binding-rods B the key may be removed from the lock and is desired to retract or unlock said bars.

In Figs. 7 and S of the drawings a modificathe means for casting and retracting the bolts is illustrated. In theseviews, as in Figs. l to 6, c2 is the main part of the binding-piece C2. B are the binding-rods, to which it is to be secured, and D the locking-bars. In this case, however, the locking-arms are operated as follows: Mounted in said bindingpiece C2 is a pinion E, which engages rackteeth e at the bottom of a recess formed in said bars adjacent to said pinion, said recesses being of such length as to permit desired movementof said locking-bars and the edges thereof preferably registering when said bars are at the middle point of their movement. The pinion E is rigidly mounted upon a shaft or axis e', which has bearings in the top and bottom, respectively, of the binding-piece C2. This shaft projects through the top of said binding-piece and a handle e2 is secured thereto, whereby said pinion may be rotated, so as to cast or retract said locking-bars D. i

Figs. 9 and l0 illustrate still another modiication of the means for operating the locking-bars. In this construction the lockingbars D are operated by means of links e, each secured at one end to one of said locking-bars D and at the other to a collar or iiange E, rigid upon a shaft e', mounted in the binding-piece C2, the points of attachment with the collar E being eccentric to the axis of the shaft e', to which said collar is secured, said links being so attached as to move said bars equal distances. The shaft or axis e projects above the top of ythe binding-piece C2 and a handle e2 is attached thereto for operating the same. In the two forms of the device lastabove described springs are applied thereto tending to cast the locking-bars, as in the form of the device first described and for the same purposes. There being no loose key in the modified forms of the device, no provision is made in constructing the escutcheon-plate for holding the same in operative position. In any form of the device the escutcheon-plate is desirably secured to the binding-piece by means of thescrews or rivets c7, which extend through said escutcheon-plate, and also by other screws .or rivets ce, binding said plate and bindingpiece together near their ends. Moreover, in all forms of the device shown the bindingrods B will be provided near their upper ends with annular grooves adapted to receive the locking-bars and permit of their being fully cast. The edges of said grooves will thus form shoulders, which will hold said binding-piece positively in position. This is designed for use only when the file is full and is to be permanently locked.

It is obviously not essential that two wedging-surfaces be employed to clamp both binding rods, as practically the same eect can` be produced by the use of a 'single wedgingsurface, as would be the case were the locking-bars D cut off at the point x, as indicated in Figs. 4 and 5 of the drawings. I do not therefore wish to limit myself to the use of a device with two wedging-surfaces adapted to engage each rod B.

I claim-- l. A temporary binder comprising the combination,'with a cover and rodssecured thereto, of a binding-piece provided with holes or perforations adapted to receive said rods, locking-bars longitudinally movable in said binding-piece, having surfaces adapted to engage said rods and lock or clamp said bindingpiece thereto, and means for actuating said locking-bars, substantially as described.
